An inverse function produces points (y,x) for every point (x,y) produced by the parent function. So to find the inverse function, you solve for the independent variable and when done switch the variable labels....
y=x+5 subtract 5 from both sides
y-5=x now switch labels
y=x-5
So if f(x)=x+5
f^-1(x)=x-5
Answer:
$7.20
Step-by-step explanation:
The first step is to convert 1 1/4 to decimal form. 1/4=0.25, which when added to the 1 gives a total weight of 1.25 pounds. Dividing this by the price to find the unit price, you get 9/1.25=$7.20 per pound of turkey. Hope this helps!
Answer:
1 5/14
Step-by-step explanation:
-3 1/6 / -2 1/3
-3 1/6 = -19/6
-2 1/3 = -7/3
-19/6 / -7/3 = -19/6 x -3/7
-19 x -3 = 57
-6 x -7 = 42
57/42 = 1 5/14
When reduced, both of these equations are
y=(-2/5)x + 7/5, which means they are the same line and therefor have infinitely many solutions
